You should have a coolant reservoir that the overflow hose runs to, the vehicle pulls coolant out of the reservoir as needed, as well as pushes it back in, could also be a stuck thermostat or a weak radiator cap, if you replace the cap make sure you replace it with one of the same pressure rating.

Olds alero leaking collant through air condtion overflow

Heater core must be leaking. It is located close together in the dash next to the ac evaporator so it can leak out through the ac "overflow" hose.

01 aurora 3.5 my coolint is running out what lins or holeses r back there where u cant see on top where u have 2 look from under the car on the passage side 2 see the leak i cant see it from top of engine.

Most likely the metal line running under the overflow tank in a front to back direction. There is a clamp that holds it in place between the collant overflow and the fuse panel, and it usually leaks there.

It appears that I am losing coolant via the overflow tank atop the radiator. The truck runs fine, does not overheat, but every so often there is a puddle of coolant under the truck. We have checked...

head gasket failure between piston seal and the cooling system causing pressure ,it will not show as water in oil but white smoke on start up from cold ,when it warms up it will tend to seal itself but eventually it will just keep boiling up

Antifreeze/water leaking . puddle underneath van already got new thermostat, radiator is full overflow box full. can't see where leak is coming from. either from below or above view is blocked by other...

May not be either. Does the van run hot? If it doesn't then the coolant when it is heated is going to the overflow reservoir and if that fills up then out the overflow line to the driveway or the garage floor but everything is O.K.

While driving mt collant temp light come on.

Check the radiator ( not hot) and overflow/fill tank for proper levels. Check under the car after parking for any leaks. The temperature is usually read at the thermostat, so it may be stuck closed , causing overheating, and the light to come on. Thermostat is an easy fix. If the car has been overheating you will need to change the thermostat anyway. The car will run fine in the summer without the thermostat , so at least take it out and see what happens.

My collant level warning say is low so i added more collant so how come the check engine lights still on?

check that the radiator is full to the top... sometimes there is a small air lock in the top of the radiator, take off the radiator cap slowly and fill it up till it overflows a little and replace the cap letting as little air as possible into the system, hopefully the light will go out. Otherwise it could be an airlock elsewhere in the system, squeeze all the pipes while the engine idles and move the water around by squeezing in a rhythm, you will feel the difference between an air filled pipe and a coolant filled pipe, check every bit of pipe is full of water with no air locks in bends or twists.

Van is going through collant but there appears to be no visable leaks. runs the fan at redlights and in town driving but not when on the highway. can smell coolant after driving van.

Get a pressure tester, and test it cold. You may be burning the coolant off before it hits the ground. Could also be literally burning the coolant in the motor.
